In addition to the above choices, motivated by the hybrid approach [1]}, [2]}, [3]}, [4]}, [5]},
the following replacements for \(\pi _a^{-2}\)  and \(\pi _a^{-1}\)  in Eq.(REF ) were also introduced in [6]},
\(\frac{1}{\pi ^2_a}&\rightarrow & \frac{64 \pi ^2 G^2\lambda ^2 \gamma ^2}{9a^4{\cal {D}}}, \\\frac{1}{\pi _a}&\rightarrow & -\frac{8 \pi G \lambda \gamma \Theta (b)}{3a^2{\cal {D}}^{1/2}},\)
